That's true, but don't forget Lengyel-Sopot. I did look just recently more carefully at the variation of E1b in various places of Central Europe and its actually not like E-V13 was there alone at all. Related E1b1b clades are practically everywhere, just at a much lower frequency. But I guess that's in some places local survival of people like the Michelsberger and related people even. Probably unrelated to the more recent spread of E-V13, but who knows for sure without a detailed analysis.
